Studies On Extract Natural Carotene And The Preparation Technology Of Related Production

β-carotene has widespread in the color vegetable and fruits,especially in carrot. Theβ-carotene are a kind of anti-oxidizing agent,having the function of counteract poison,and a indispensability nourishment that supports the healthy of human body.It also has the function of anti-cancer,preventing cardiovascular disease and anticaducityThe research is having a foothold in actual circumstance of the resources advantage and productions of the country.The research aim at the world to carry on naturalβ-carotene's extraction and develop the related applied product to demand the modern crowds to nourishment and health care and to demand enlarge continuously market of the naturalβ-carotene currently.The study as follows:1.Study to build up the method:Ultrasonic Extraction to enhance the sample handle,The RP-HPLC examines the method system of theβ-carotene.The HPLC system was consisted of Inertsil ODS-3,C₁₈(4.6 mm×250mm,5μm) and UV detector set at 450nm.The mobile phase:V(CH₃OH):V(CHCl₃)=65:35,Flow rate:1.2 mL/ min.Temperature of Chromatography:30℃and Inject volume:10μl.The optimum condition has been obtained by Uniform design method as follow:X₁(Ratio of solution and solid)=15:1(v:w),X₂(Extract time)=30min,X₃(The power of ultrasonic)= 90w,X₄ (Extract temperature)=40℃,X₅(Extract degree)=3 times.2.Study the carrot powder for raw material,Distill theβ-carotene with ethanol which are innocuity and dissolve better.The optimum condition has been obtained by Universal rotary orthogonal experimental design method as follow.X₁(Ratio of solution and solid)=30:1(v:w),X₂(Extract time)=45min,X₃(The power of ultrasonic)= 60w,X₄(Extract temperature)=45℃.Develop a new path Extractβ-carotene. 3.The microcapsule of naturalβ-carotene not only keep the carotene but also Strengthen its stability overcome the destructive factor.At the same time to make up for the shortage of difficult dispersion in the aqueous solution.Study on the wall and core materials of microcapsule.Adopt the sprays-drying method to product carotene microcapsule.The optimum condition has been obtained by Uniform design method as follow:X1(The dextrin:The maltose)=8:2(w:w),X2(Corematerials:Wall materials)=4:6(v:w),X3(Wall materials:Water)=1:2.5(w:v),X4(The temperature of entrance)=200℃.Carry on the research to the stability and quality of carotene microcapsule product.4.Study to make use of the microcapsule powder of naturalβ-carotene to make into the Oral effervescent tablets aiming at the child,old people and the person can't swallow Adopt orthogonal design method to optimum technology condition as follows:X₁(The additive of microcapsule powder)=25%,X₂[The acid(Citric acid:Malic acid)=1:1]=35%,X₃[The alkali(NaHCO₃:Na₂CO₃)=1:9]=20%.Carry on the research to the product quantity at the same time.
